I get this wicked magenta and black artifacting when in Photoshop CS4 on Mac when I resize the window. It doesn't affect the image canvas, but it's on the artboard all around it.


  • Early 2008 Macbook Pro
  • OS X 10.5
  • 4GB RAM
  • GeForce 8600M GT (512MB video RAM)

Weird. Which hardware/software do you have specifically? –  slhck May 24 '11 at 15:28
Nothing really special or unusual. Early 2008 Macbook Pro running OS 10.5, 4GB RAM, 512MB Video RAM, GeForce 8600M GT. Photoshop CS4. –  milkmood May 24 '11 at 15:36
I'd check my video card drivers, if I were you. If it starts happening in other programs then your graphics card might be on its way out... A weird bug, to be sure :-/ –  Django Reinhardt May 24 '11 at 19:06
Photoshop is the only program that this happens in, and if I hide PS and then unhide it again, it's gone. It's happened since I installed PS 2 years ago. Not a showstopper, but an inconvenience since I depend on the gray background for contrast. –  milkmood May 25 '11 at 17:16
And it doesn't happen all the time. I can't pinpoint any commonalities between occurrences. Tumbleweed. –  milkmood May 27 '11 at 17:40
